Bearing holder for bearings mounted on journals

Abstract

A bearing holder for bearings mounted on journals includes a lower support socket secured to a frame, and a cover part pivotally connected with the socket. The cover part is able to be locked in a shut position, folded onto the bearing positioned in the support socket. In order to provide a bearing holder of this type, which makes possible the removal and insertion of the journals without releasing the cover parts by hand, and without having to be pivoted and locked for the purpose of opening and shutting, cover parts are pivotally bearinged on two upper lateral parts of the support socket about axes which are parallel to the journal. Such cover parts include an upper, longer arm and a lower, shorter arm of a two-armed lever. The lower arm forms an actuating part, which, in the folded back, opened position of the cover part, extends into the interior of the support socket, so that by lowering the bearing, which abuts against the same and is placed on the journals, into the support socket, the bearing pivots the cover parts into its shut position, in which the latter has its inner, arcuate sides in snug engagement with the bearing. Thus, the cover parts which, in this manner, are folded into their shut setting, and have their end faces abutting against each other, are provided with an automatic device locking the cover parts together.

We claim: 
     
       1. A holder for a bearing of a printing image carrying cylinder and an inking roller of a printing press, comprising: a lower support socket, said bearing adapted to be lowered into said lower support socket,   a pair of two armed levers, each forming one of first and second cover parts pivotally connected with the lower support socket, said cover parts being able to be locked in a shut position, wherein they are folded onto said bearing when it is positioned in the lower support socket, said first and second cover parts being supported on two upper lateral parts of the lower support socket for pivotal movement about axes which are parallel to at least one bearing journal, each of said cover parts formed by an upper longer arm of one of said two armed levers, a lower arm of each of said two armed levers forming an actuating part which extends into an interior of the lower support socket when the first and second cover parts are in folded back, opened positions so that by lowering the bearing into the lower support socket so that it abuts against the lower arm of each of said two armed levers and is placed into the support socket, the cover parts are pivoted into shut positions, in which inner arcuate sides of the cover parts are in snug engagement with the bearing, and   an automatic locking drive for locking the cover parts together once the cover parts are pivoted into said shut positions so that end faces thereof abut against each other.   
     
     
       2. A holder as claimed in claim 1, wherein said automatic locking drive further comprises a bolt having a head which is supported by at least one bearing in one of said cover parts, said head being provided with a rotary and clamping drive and fitting behind a bifurcate abutment part of the other of said cover parts. 
     
     
       3. A holder as claimed in claim 2, characterized in that the rotary and clamping drive includes a pneumatic rotary piston and cylinder unit. 
     
     
       4. The holder as claimed in claim 1, characterized in that the cover parts are secured in said folded back, opened positions by abutments provided on the cover parts or on the lower support socket.
